Britain’s energy system has fallen victim to a cyber-attack targeting the IT infrastructure used to run the electricity market.

The electricity system’s administrator, Elexon, confirmed that it was affected by a cyber-attack on Thursday afternoon but that the key systems used to govern the electricity market were not affected.
A spokesman for the energy system operator said electricity supplies had not been affected, and there were “robust cybersecurity measures in place” to make sure the UK continues to receive reliable electricity.

“We’re aware of a cyber intrusion on Elexon’s internal IT systems. We’re investigating the matter and any potential impact on our own IT networks,” he said.
